Issue
NinjaOne is reporting issues with Windows Management Instrumentation (WMI) performance.
Environment
- NinjaOne Agent
- Microsoft Windows
Cause
The NinjaOne agent relies on WMI calls for all of its reporting. As such, if there are existing WMI issues on a machine (as documented in the Microsoft community), NinjaOne will highlight them.
- Performance counters can often be the culprit. Check out this Microsoft documentation on rebuilding performance counter library values.
- The WMI Performance Adapter service not running, or running as a user rather than as System, can also cause issues.
Resolution
Windows provides information about setting up WMI activity logging at WMI Troubleshooting - Win32 apps | Microsoft Learn (external link).
Additionally, you should run sfc /scannow to eliminate corruption as a possible cause.
